SPECIFICATION forming part of Letters Patent No 368,009, dated August 9,1887.

` Application led April 26, 1887. Serial No. 236,188. (No model.)

To all whom. it may concern:

Be it known that I, CHARLES Ross, Jr.,a citizen ofthe United States,residing at Brooklyn, E. D., in the county of Kings Vand State of NewYork, have invented certain new and useful Improvements inBelt-Shifters, of which the followingis aspecitication, reference beinghad therein to the accompanying drawings, in which Figure l represents aside view of part of a paint-mixerprovided with my improvement.

` Fig. 2 is a vertical transverse section through p and the inventionconsists inthe peculiar con- .the vertical shaft ot' the paint-mixer.

ters the hole b.

struction, arrangement, and combinations of parts, hereinafter moreparticularly described, and then definitely pointed out in the claim.

Referring to the details of the drawings, which show the preferableplans of carrying out my improvement, A represents the shaft of anordinarypaint-miXer run ning in suitable bearings, B B', andcarry-ing'the bevel-gearO, meshing with a larger bevel-gearD, set onneath the bearing Bris a holder, L, cast or otherwise formed or attachedto the'frame or standard, having asquare hole, b, adapted to receive abar, E, which tits in said hole and is held vthere by a set-screw, F.This bar is shown in Figs. 1 and 2 as bent upward at e and as having ayhorizontal arm,e, substantially at right angles to that part of bar Ethat en- On this arm e works a slide, G, preferably provided with ahandle, g, and having on'its under side two holes which receive and holdthe ends h of the belt guide or yoke H, which ends are securely fastenedby means of the nuts l', screwed onto the ends h on each side of theslide G, and thus the yoke His rigidly held in said` slide G.

Near each end of the arm e is a pin,J, which lacts as a stop to preventthe slide G from travof the bar E passing into a hole forming part ofthe machine I use a separate holder, L, pro- `vided with holes Z,through which bolts may be passed to fasten the same to any machinedesired.

I do not limit myself to the exact construction shown, as it is evidentthat the form of the holder L may be varied to suit different machines;nor do I limit myself to a square bar, (although l prefer it,) as it isobvious that bars of other forms may be used-as, for instance, a iiatbar or a round bar provided with somelmeans for preventing the slidefrom vturning thereon.

I prefer to make two sets of holes I in the arm e' at right angles toeach other, as shown in Fig. 3, (one set being shown in dotted lines,)in order that the shifter may be more readily adapted to differentmachines; but this is not necessary where it is designed for somespecial machine, as one set of holes is all that is re-j quired.

The key will prevent the creeping of the belt on the tight pulley andthe starting of the machine, which frequently occurs with the old styleof shifter, tothe great dangerof the operator.

Instead of the key a setscrew may be used, or a spring-catch that theoperator may draw out of a notch on the arm e as he places his hand onthe handle g.

It will be seen that the bar E may be pushed in or out of the holder asdesired, and secured by the set-screw to allow larger or smaller pulleysbeing used, as required, or to suit the angle on which the belt runs.Further adjustments may be had by bending theY bar E at different anglesor by transposing the slide on the bar, so as to bring the guide or yokeH above or below or on opposite sides of the arm e; or the guide itselfmay be bent at different angles to'suit circumstances. It will -I OOalso be seen from the foregoing that my inhar E, bent substantially abright angles and vention makes a very convenient belt-shifter', havingone arm adjustable in said holder, Subwhieh can be sold as an article ofmanufacstantially as and foi` the purpose specified. ture, as it isreadily adapted to any machine, In testimony whereof Iafix my signature,in

5 whether new or old, and one tl1at,wl1ile compresenee of two witnesses,this 25th (lay of 15 paratiively cheap, will be very durable and April,1387.
